I need to know why I am still receiving login attempts from other sources on my account despite my changing the password multiple times within the last week.

Hi,

I'm sorry to hear that you're experiencing this issue. Login attempts typically occur when your email address has been leaked on the dark web. As long as these attempts are unsuccessful, your account remains safe. To prevent this, create a new alias for your account and set it as the primary. Then, configure your account settings to require sign-in only with this new identifier.

  1. Log in to your Outlook email account: Outlook.com or https://account.live.com
  2. Under your profile photo, click on "My Microsoft account."
  3. On the new page, click "Your info" and locate the "Account info" section.
  4. Click "Sign-in preferences" and, under "Account aliases," add a new email address or phone number that is not publicly known.
  5. Ensure it’s a valid and accessible contact.
  6. After adding, select "Make primary" to set this new email or phone number as your primary sign-in.
  7. Scroll to "Change sign-in preferences," uncheck your current Outlook email address, and check the box for your new login method.

Important: DO NOT delete the current/old email address

This will keep your email account active for sending and receiving messages while preventing login attempts.

    The answer from Estrella721 is good advice. But you need to be aware that Microsoft has broken the "Default From" setting in New Outlook and Outlook Web. This means that for any new email, the From will default to your Primary alias and you will want to change it, each and every time, by clicking on the From drop-down and pick your non-Primary Alias.
